Krug is a Champagne house based in Reims, France, producing exclusively sparkling wines within the Champagne appellation. The house operates under the traditional méthode champenoise, crafting their champagnes from the three classic Champagne grape varieties: Chardonnay, Pinot Noir, and Pinot Meunier.

The Champagne region, where Krug is located, is renowned for its unique terroir combining chalky soils, cool climate, and specific grape varieties that create the foundation for premium sparkling wine production. Champagne houses typically focus on blending wines from different vineyards, vintages, and grape varieties to achieve consistency and complexity. The region's strict appellation controls govern everything from grape growing to production methods, ensuring the distinctive character of true Champagne.

Krug's current range demonstrates the house's approach to both vintage and non-vintage expressions. Their Grande Cuvée represents a multi-vintage blend, while their Rosé offers the complexity of all three Champagne grape varieties in a prestige cuvée format. The 2006 Vintage showcases wines from a single exceptional year, reflecting the specific conditions and character of that harvest.

In 1668, Dom Pérignon is said to have discovered how to make sparkling wine; today his technique is used the world over, although Champagne continues to make some of the finest. France’s most northerly wine region, Champagne is now home to 15,000 growers and 290 ‘houses’. A blend of grape varieties is usually required: white Chardonnay to add fruit and elegance, and two reds – Pinot Noir and Pinot Meunier – to provide body and backbone.

Champagne is a region in northeastern France, approximately 140 kilometers northeast of Paris, defined by strict geographic boundaries established under French appellation law. The region's cool continental climate and chalky soils create conditions uniquely suited to sparkling wine production. The designation "Champagne" is legally protected and applies only to wines produced within these delimited boundaries using prescribed methods.

The region's chalky subsoil—composed largely of Cretaceous limestone—drains rapidly and reflects heat, helping to ripen grapes despite the cool climate. Three grape varieties dominate: Chardonnay, Pinot Noir, and Pinot Meunier, often blended together though Blanc de Blancs wines use Chardonnay exclusively. Champagne's signature method involves a secondary fermentation in bottle (méthode champenoise), where yeast and sugar create carbonation and develop complex flavors over time. Extended aging on the lees further develops texture and aromas. Producers classify vineyards into Premier and Grand Cru designations based on historical quality assessments, and finished wines are labeled by dosage level—ranging from Extra Brut (bone dry) through Brut, Sec, and Demi Sec (progressively sweeter).

Champagne wines are characterized by high acidity, fine bubbles, and layered complexity. Typical flavor profiles include green apple, citrus, and chalk minerality in younger or lighter expressions, evolving toward brioche, toast, and honey notes with bottle age. The interaction between the wine's acidity, the persistent effervescence, and the autolytic characters from yeast aging creates distinctive textural finesse that distinguishes Champagne from other sparkling wines produced elsewhere.
